THREAD-CUTTING SEWING-THHVIBLE.

SPECIFICATION forming part of Letters Patent No. 633,635, dated September 26,- 1899.

Appiication flied nemterzmses. Smalle- 699.918. (.NomodeD To (LZ2 whom t wtay concern.-

Be it known that I, FREDERICK G. BON- VFILS@ citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Thread- Cutting Sewing-Thimbles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in thread-cutting thimbles, my object being to provide a device of this class which shall be simple in construction, economical in cost, reliable, durable, and eflicient in use; and to these ends the invention consists of the fea-- tures hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, inwhich is illustrated an embodiment thereof.

In the drawings, Figure lis a side elevation of my improved thimble. Fig. 2 is a section Itaken on the line a: a', Fig. l. Fig. 3 illustrates the thimble in use. Fig. 4 is a vertical section taken through the thread-cuttin g 3o slot of the thimble, which is shown on a larger scale,

Similar reference characters indicate corresponding parts in the views.

Let the numeral 5 designate a thimble, which is provided with a thread-cutting slot or groove 5, open on its curved surface, but

not extending to its free edge. As shown in the drawings, this slotis formed in the smooth or plain part of the thimble. The slot is preferably undercut toward the free edge of the thimble to facilitate the catching and severing of the thread. The edge of the slot may be beveled, as shown at 5C, to give it any desired degree of sharpness.

Itwill be observed that instead of cutting entirely through the slot of the thimble, as shown in Figs. 2 and 4, a groove may be made therein which will perform equally Well the thread-cuttin g function. The only difference between the groove and the slot is one of depth or degree. Hence the construction is substantially the same in both cases.

It must be understood that I do not limit the invention to the details of the construction herein shown, as I am aware that many changes may be made without departing from the spirit of the invention.

Having thus described my invention, what I claim is- 1. A sewing-thimble having a thread-cutting slot or groove formed in its curved surface and undercut for the purpose set forth.

2. A sewing-thimble provided with a threadcutting slot or groove undercut in the direction of, but not to, its free edge.

In testimony whereof I affix my signature in presence of two witnesses.

FREDERICK G. BON FILS.
